Understanding mining.
How a mine is found, built, worked and returned.
The stages.
A mine is measured in decades.
Exploration
Exploration is mapping, sampling and drilling. Most ground that is explored never becomes a mine, and from the outside this stage looks like very little: a few vehicles, some drill pads, holes that get filled in.
Feasibility and permitting
Studies establish whether the resource can be recovered at a cost that works and a standard that holds. Permits, environmental assessment and community consultation happen here, before anything is committed. This is the stage where objections can still change the plan.
Construction
Access roads, power, water management, processing plant and waste facilities. This is when a district notices a mine arriving, and when local employment and procurement start in volume.
Production
The years the mine is actually working. Ground is opened in phases, which is what makes the next stage possible.
Progressive rehabilitation
Progressive rehabilitation. Worked-out areas are reshaped, topsoil returned and replanted while other areas are still producing. A mine that leaves all of this to the end usually does not do it.
Closure and aftercare
Plant removed, land handed back, and monitoring that continues after the company has gone. Closure is a plan written at the start, costed throughout, and tested at the end.
